BED-SPRING FASTENER- Specification of Letters Patent.

Patented April 17, 1906.

To all whom it may concern:

Be it known that I, ROBERT NAYsMrrH, a citizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inBed-Spring Fasteners, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inbed-spring fasteners; and the invention relates more particularly to anovel construction used in connection with the manufacture ofbed-springs.

The present invention aims to provide positive and reliable means foreffecting a perfect holding of a spring woven-wire fabric in a frame,and in this connection I have devised a novel construction which permitsof the parts of the frame and its spring woven fabric being easily andquickly assembled and held to maintain a rigid, strong, and durableconstruction. To this end I have provided a metallic frame for springwoven-wire fabric which will permit of the same being manufactured at acomparatively small cost, and in connection with this construction Ihave devised novel means for supporting the spring-frame upon a bed.

With the above and other objects in view, which will more readily appearas the nature of the invention is better understood, the same consistsin the novel construction, combination, and arrangement of parts, to behereinafter more fully described and claimed.

The essential features of the present invention are necessarilysusceptible to structural changes without departing from the spirit andscope of the invention; but the preferred embodiments are illustrated inthe accompa nying drawings, in which- Figure 1 is a top plan view of aspring constructed in accordance with my invention, illustrating thesame supported by a bed. Fig. 2 is a sectional view, taken on the line was of Fig. 1, looking in the direction of the arrow A of said figure.Fig. 3 is a similar view, taken on the line y y of Fig. 1, looking inthe direction of the arrow B. Fig. 4 is a sectional view, taken on theline w w of Fig. 1, looking in the direction of the arrow C. Fig. 5 is aperspective view of a malleable casting forming a part of my improvedconstruction.

Fig. 6 is a perspective view of the same looking at the rear side of thecasting, and Fig. 7 is a top plan view of the casting.

To put my invention into practice, I employ a construction consisting offour castings 1, two pieces of tubing 2, two angle-bars 3 3, a webbingof wire 4, or, as it is commonly known, woven-wire fabric, and numerousrivets or bolts and nuts to secure the parts together.

The castings 1 are identical in construction, and by referring to Figs.5 to 7, inclusive, it will be observed that the malleable castingconsists of a substantially keystone-shaped plate 5, the lower end ofwhich is provided with a tubular extension 6, which is further joined tothe plate 5 by a vertically-disposed rib 7, this rib extending from thetop of the tubular extension 6 to the top edge of the plate 5. Thetubular extension 6 is formed at right angles to the plate 5, and theinner configuration or area of the tubular extension 6 conforms to anoval, as clearly illustrated in Fig. 3 of the drawings. The rear side ofthe plate 5 is cut away, as at 8, and provided with atransversely-disposed slot 9, the formation of this slot providing aflange 10, the object of which will be presently described. The one sideof the plate 5 is provided with a right-angular extension or lug 11. Thetop of the rib 7 is provided with an upwardly-extending protuberance orpin 12, the object of which will be presently described. Two of each ofthe castings are joined together by the longitudinally-disposed sectionsof tubing 2, (illustrated in Fig. 1 of the drawings,) and incross-section this tubing is preferably formed oval to correspond to theoval opening of the tubular extension 6 of the castings, thisconstruction being employed to prevent the castings from rotating uponthe ends of the tubing 2. In practice these sections of tubing form thelongitudinally-disposed sides of a frame which supports the web-lace 4.

The angle-bars 3 3 are adapted to be retained upon the castings 1 by theflange 10 and the protuberances or pins 12 of the castings. The ends ofthe angle-bars 3 are provided with openings 14 14, which are adapted toreceive the pins 12 12 of the castings, as clearly illustrated in Fig. 4of the drawings. The vertical portion of each of the bars 3 when thebars are placed on the castings is bars 3 3.

adapted to seat in the slots 9 of said castings and coincide with theplate 5 of each casting. Strips of metal 15 15 are employed for securingthe fabric 4 to the bars 3 3, and the edges of the fabric 4 are clampedbetween the strips 15 15 and the horizontal portion of the anglebars 3by a plurality of rivets 16 or the like fastening means, which areplaced at intervals along the bars 3 3 to firmly retain the ends of thefabric 4 in engagement with the The fabric 4 may be made of any desiredweave, and I employ a conventional form of woven Wire in connection withmy improved construction.

In assembling the different parts of my improved construction thecastings are first placed upon the ends of the tubings 2, these tubingshaving been out the proper length to obtain the desired length ofbed-spring. The bars 3 3, which have been placed upon the ends of thefabric 4, are now positioned upon the castings, one of said bars beingplaced in position within the slots 9 9 of the castings and upon thepins 12 12, at which time the opposite end of the fabric is stretcheduntil the bar 3 can be placed in the slots 9 9 of the castings 1 1. Inthis operation the bar 3 is further retained in engagement with thecastings 1 1 by the protuberances or pins 12, which insure a furtherlocking of the bar 3 within the slots 9 of its respective castings. Tofurther insure a positive engagement of the bar 3 with its castings, theends of the malleable protuberances or pins projecting above the bar canbe flattened to form a rivet, which will permanently hold the fabric 4in a taut condition between the bars 3 3. By this construction it willbe observed that a substantially rectangular bed-spring and frame isformed, and inFig. 1 of the drawings I have illustrated the same inconnection with a bed 17. It will be observed that when the spring ispositioned upon the bed the right-angular lugs or projections 11 engagethe side rails 18 18 of the bed near the foot and head pieces thereof,thus firmly supporting the spring-frame upon the bed.

I desire to call particular attention to the simplicity of themalleable-iron castings and to the manner of fastening the fabric to itsframe. "By this construction I am enabled to manufacture the castingsand their appurtenant parts at a comparatively small cost, and thesimple manner in which the different parts of the bed-spring areassembled permits of parts of the bed-spring being shipped ortransported in a knocked-down condition, it only being necessary toassemble the different parts when the bed-spring is to be used.

I am aware that heretofore it has been the customary practice to usepieces of tubing similar to the tubing 2. It has been the practice touse circular tubing, which was secured in different kinds of castings bykeys but by the construction of the tubing 2 in cross-section and theconstruction of the tubular extensions 6 of the castings it -will beobserved that the keys heretofore used are dispensed with and that thetubing will be prevented from rotating independently of the castings 1.

It will be apparent from the above description that I have devised anovel form of bed-spring frame adapted to support a fabric. Inconnection with the castings used I do not care to confine myself to themanner of supporting the same upon a bedframe, as in some instances thecastings may be formed integral with the frame of the bed, which wouldpractically serve the same purpose. The tubular extensions of thecastings having oval openings formed therein may be dispensed with andthe lower end of each plate provided. with an oval opening, thisconstruction being of a more simple form than that illustrated.
